As we gaze enraptured into a marine pool—seeing here a sea anemone, its iridescent blue-green tentacles rhythmically searching for food, and there the ludicrous side-winding hermit crab, his home a borrowed sea snail shell—we suddenly sense that natural selection explains too much! The brown rockweed; green, red, and coralline algae; sun, blood and purple starfish; sea urchins; sand dollars; many richly beautiful red beard sponges—surely the sea tides, daily giving this pool in the craggy rock its place in the sun for an hour or so, could not, by selection, develop such marvelous diversity as this.

Elliott G. Watson, British zoologist writing for The Saturday Evening Post (“Hidden Heart of Nature,” May 27, 1961, pp. 32–33), lists four examples of life histories that orthodox evolution theories simply cannot explain. We mention only the coral reef inhabiting crab whose claws are so small as to be useless as weap-one. But the backward curving teeth of the claws grasp the slippery bodies of small anemones and detach them carefully and without injury from the rocks. Thus held close to the mouth of the pirate crab, the anemones continue to spread their tentacles and to capture small creatures, which the crab, with his free front pair of walking legs, removes as dainty tidbits. Those he dislikes he leaves for the anemones, which are finally released unharmed. Are these adaptations to be explained by chance mutations? Did a chance modification of the claws prompt some ancestral crab to detach an anemone for the mere fun of the thing and by chance hold it near its mouth? If so, we must then assume that the crab passed on to its offspring this behavior tendency, and through natural selection the crab species thus developed their close ...
